PHONOGRAPH.

To'aZZ whom it may concern:

Be it known that I, HARRY L. .CAssaRn, a

citizen of -'the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Phonographs, of which the, following is aspecification.

My invention is designed to provide a talking machine or sound producingdevice of the kind known as phonographs, graphophones and gramophones.

' It relates more particularly to the gramophone type in which a diskrecord is .employed. My idea, is to provide a cheap toy of this kind forreproducing articulate spe'ech, muslc, songs, &c., in WlllCh, instead ofa definitely driven motor" mechanism, the device is to be held inthehand and the necessary movement for causing-the traverse of the needlein the groove of the record is secured by a whirling action in the hand,one of the 'parts being eccentrically weighted to cause, by centrifugalaction, a' movement between the needle and the record. U. S.

Patent No. 836,470 was granted to E. C. Smith for a device of thisgeneralcharac ter. My invention is designed to be an improvement uponthis device, which permits of the use of cheap ten cent records andsecures a muchclearer and louder tone and at a less expense, as will bemore fully de scribed hereafter with reference to the drawing, in which:

Figure 1 is a perspective view of the complete device. Fig. 1 is asectional end view of the open end of the sound box. Fig. 2 is anenlarged under side view of the sliding bottom of the sound box anditsattachments. Fig. 3 is a view of the blank from which the needleholder frame is fashioned. Fig. 4 is a view of the needle'holder, andFigs. 5 to 8 are views showing modifications.

In theidrawing, Fig. 1, A is a resonant box preferably square in crosssection and of elongated form and open at one end. The

bottom B of the box slides longitudinally,

in guideways at the lower longitudinal edges of the box. 1

D is an ordinary disk record of gramophone type which is clamped rigidlyto a basic table T on handle C in right angular position.

.E is an axial stem, screw threaded at its lower end 0 to enter thehandle Cv inaxial Specification of Letters Patent.

position and having a small enlargement or flange Z) which clampsthedisk to the end of the handle when the screw stemis turned in and whichpermitsthe quick and easy substitution of new disk records. A woodenblock or hub (it embraces the axial stem E within the, box and isrigidly connected to' the stem by a setscrevv just beneath the top ofthe box so as to hold the box a predetermined distance above the diskrecord. On the lower side of the sliding bottom B of the box is rigidlymounted a light diaphragm F of the. same general form and structure asthe lldof a pill box made of any vibrating material, paper or cardboardserving the purpose for cheap construction.

to hold the shank of the needle and which needle holder is clamped tothe frame by a set-screw and is made to pinch and hold rigidly theneedle. The horizontal mem ber of the needle holding frame has at itsouter end a spur s which rests against the diaphragm through theintermediary of a For the cheap and convenient formation of this needleframe it is stamped in one'piece of thin metal in the form of the blankshown in'Fig. 8, the lug Z of the blank in Fig. 3 forming, when bentaround, theneedle. holder H of Figs.

2 and 4.

Referringnow to Fig. 1, it will be seen that the sound box A turnsfreely on the stem E as an axis and the needle rests in the spiralgroove of the record D, the center of gravity of the box being on oneside of the axial stem, so that When the handle C isgrasped inthehand'and a whirling or gyratory motion is given to the box the latterswings around the axial stemE and the needle traverses the groove in thenon rotating disk and thus the record of the disk is reproducedby thevibrant quality of the diaphragm and sound box, Which latter acts like aviolin body to greatly amplify and clarify the sound, Whether it bearticulate speech or music.

I In carrying out my invention Itmake various modificatlon of the same.Thus. for m- 25 also givesa diverging horn-like outlet for stanceinstead of making the whole bottom of the box slidable, the box may bemade in two telescopic or collapsible sections as in Fig.

5, one section being hung on the axial stem and the other being arrangedto carry the needle and. capable of progressive motionin radialdirection to the central axis as theneedle traverses the groove of therecord. Furthermore, the sound box may be constructed as n F 1g. 6, inwhich the box is I closed on all sides .and has slotted holes like. thef-holes of. a violin, to let the sound out. In this case the needle w isattached 2 to a button 1 and this, see Fig. 6f, is connected by tworubber covered pins 2 to a slide 6 inside the box. The rubber covered.pins aslide in a slot u' in the box toward or away from the axialcenter "v.' In Fig. 5 one side of the movable-box section forms thediaphragm and in Figs. 6 and 6 the button 3 and attached slide t formthe diaphragm.

Anbthen modification, seen in' Fig. 7, shows the sound box in triangularor Wedge shape. This not only makes the outer end heavier for-bettercentrifugal effect, but

the sound, the box'being open at its'larger both supported -uponandcarried by the relation thereto.

volves and the disk record, is relatively stationary.- It is obviousthat the sound box may, as'in Fig. 8, be relatively stationary and thedisk rotated 'byproviding it With.

an eccentric -w'i ht. r and fswivelin it on the axial stem, and clampingthe sound box.

in such case rigidly to the handle by nuts nn.

In all of these formsthe resonant sound box, of Violin action, is,employed and the sound box is provided wlthjtwoparts capable ofrelativeprogresslve movement toward or away from the center in radialdirection to permit the proper traverse or progression of the needle inthe groove of the disk record, the needle I and diaphragm being soundbox but being sli dably adjustable in WhatIclaim is: Y 1.
